|
nuclear fusion |
atoms fuse together to form a larger atom, results in a release of energy |
|
|
HYDROGEN ATOMS |
fuse together to form a helium atom |
|
|
fission- |
the splitting of an atoms nuceleus into smaller nuclei, results in a realase of energy |
|
|
atoms decay and do what |
create heat |
|
|
conduction |
the movement of heat energy in solids by its contact with a hotter object |
|
|
convection- |
the movement of heat by currents in liquids & gases because of tempature and density differences |
|
|
radiation |
the transfer of heat in gases or a vaccum in the form of waves |
|
|
energy in- |
tempature increases density decreases volume increases pressure decreases atoms move faster and get further apart |
|
|
energy out |
pressure increases volume decreases density increases tempature decreases atoms move close and get slower |
|
|
tempature- |
is the measure of how fast atoms are moving |
|
|
density- |
is the measure of the number of atoms in a given area |
|
|
volume- |
is the space a set number of atoms occupy |
